HALO Compact User Manual 

V7 December 2019 

12.0 – Powering the System 

As  a  passive  loudspeaker,  HALO-C  can  be  used  with  any  amplifier  and  processor 
combination.  The information below details configuring a DQ Series amplifier for HALO-C 
and  HALO-CS  enclosures  specifically.    Please  refer  to  the  DQ  Series  User  Manual  for 
detailed information on using the amplifiers and the System Engineer software. 

12.1 - Amplifier and Processing Requirements 

12.1.1 – Amplifier Requirements 

We recommend using the DQ Series of advanced system amplifiers, or a 3

rd

 party 

amplifier in conjunction with the DSC48 controller.  If using a 3

rd

 party amplifier, please 

take note of the recommended specifications: - 

Product 

 

RMS Power Handling   

Recommended Min. Amplifier Power 

HALO-C 

 

500W @ 8 ohms 

 

1000W @ 8 ohms 

HALO-CS 

 

1000W @ 8 ohms 

 

2000W @ 8 ohms 

These amplifier powers can be scaled up – for example for running four HALO-C 
enclosures in parallel from the same amplifier channel, we would recommend an amplifier 
capable of delivering 2500-3000 watts into a 2-ohm load. 

NOTE: 

A small amplifier working too hard is much more likely to damage your loudspeakers than 
a large amplifier working well within its limits!
